Method and system for mobile receiver antenna architecture for handling various digital video broadcast channels

Abstract

A method for an antenna architecture may comprise receiving at a first radio frequency integrated circuit (RFIC) integrated within a mobile terminal, first signals via at least a first antenna, where the first signals may comprise signals within a 2100 MHz band. Second signals may be received at a second RFIC integrated within the mobile terminal via at least one of the first antenna and at least one other antenna, where the second signals may comprise signals within at least one of an 1800 MHz band and a 900 MHz band. Third signals may be received at at least a third RFIC integrated within the mobile terminal via at least one of the first antenna and at least one other antenna, where the third signals may comprise VHF / UHF broadcast signals within at least one of a DVB broadcast band, an ATSC broadcast band and an ISDB broadcast band.

AI Technical Summary

Benefits of technology

The patent describes an antenna system for a mobile phone that can handle various digital video broadcast channels. The system includes multiple RFICs and antennas that work together to handle signals in different frequency bands. The first RFIC is a WCDMA / HSDPA RFIC that works with a first antenna to handle signals in the 2100 MHz band. The second RFIC is a GSM RFIC that works with a second antenna to handle signals in the 1800 MHz band. The third RFIC is a DVB RFIC that works with a third antenna to handle signals in the DVB VHF / UHF broadcast band. The fourth RFIC is an ATSC RFIC that works with a fourth antenna to handle signals in the ATSC VHF / UHF broadcast band. The fifth RFIC is an ISDB RFIC that works with a fifth antenna to handle signals in the ISDB VHF / UHF broadcast band. The system also includes circuitry and filters to process the signals and ensure optimal performance. Overall, the antenna system allows for seamless reception of digital video broadcasts and provides improved quality and reliability for mobile phone users.

Problems solved by technology

One limitation has been that broadcasting may often require high bit rate data transmission at rates higher than could be supported by existing mobile communications networks.

There are also significant challenges in deploying broadcast services to mobile user equipment.

Another consideration is the Doppler effect in moving user equipment, which may cause inter-symbol interference in received signals.
